What Causes Arm Pain, Headache And Temporary Loss Of Memory?

Possible transient global amnesia but stroke and seizure should be excluded
Detailed Answer:
I read your question carefully and I understand your concern.
One possibility judging from your description that episode does look like what is called transient global amnesia (TGA), a sudden, temporary loss of memory without a cause like stroke, trauma or seizure to explain it. The origin of TGA is not clear, there have been hypothesis considering stroke, epilepsy or migraine as its possible cause, but none was proven by studies.
If indeed it is a TGA case the prognosis is good, meaning in most cases the episode is isolated or very rare and no treatment is needed. However it is essential to exclude other possible causes such as stroke or seizures which may manifest with such an episode. For that reason a neurological physical exam as well as head imaging by CT or MRI (if your pacemaker permits it MRI is preferrable) is recommended, so you should present at the ER. Some routine blood tests such as blood count, glucose, electrolytes, creatine kinase as well as an EKG are also needed.
I remain at your disposal for other questions.
